Hi, Mark,

I was reconstructing GNU software building environment.
I put 32 bit code in /usr/local/GNU and 64bit ones in /usr/local/GNU/amd64.
I sometimes had to specify "-I/usr/local/GNU/amd64/include -L/usr/local/GNU/amd64/lib",
but it was harmful.
Now I do not have to use them in almost softwares.

As the result of this, backtrace of guile has got easy to understand.
"Segmentation Fault" happens in line 895 of vm-i-system.c,
  ret = subr (sp[-1], sp[0]);

Whole the backtrace is:
  [1] __lwp_kill(0x1, 0x6, 0xffffffff89b048a0, 0x7fffffc5338e, 0x6f00312e6f732e63, 0x612f6e00312e), at 0x7fffffc52a9a
